Bulk fast5 recompression on MacOS
Hello,
I am having several issues working with VBZ-compressed bulk fast5 files on MacOS.
-
Instructions to install the vbz plugin on MacOS are extremely poorly documented.
-
The ont_fast5_api is advertised as a tool to manipulate fast5s, but doesn't work to recompress bulk fast5 file. However, this isn't stated anywhere in the documentation, further adding to the confusion.
-
My specific issue, after managing to install the vbz_compression plugin:
I am working with bulk fast5 files on MacOS, and trying to recompress from VBZ to GZIP so I can analyse the files using my own pipelines.
The command I am using is:
h5repack -f GZIP=1 input.fast5 output.fast5
This returns the following errors:
Warning: dataset <#dataset> cannot be read, user defined filter is not available
Thus, I am unable to recompress the files.
Any help would be appreciated - thanks in advance.
